A discussion is made of the optimization of a bilinear programming.

The features of the design approach are that the coupling function between water utilization network and heat exchange network is considered;in the first stage,the step-by-step double-linear programming method is employed for the design of water utilization network targeting both minimum water consumption and minimum energy loss,realizing the minimum water consumpt.

Considering the influences of transfer benefit policy on the public traffic demand and routing decision for passenger travel in a transit network,a bi-level nonlinear programming model was introduced.
